  • Publication number: 20160007175
    Abstract: In compliance with regulatory requirements imposed on multicarrier wired/wireless network carriers, the disclosed system receives input representing a selection of a street address to be used as a current location associated with a user identity. The system determines an expiration date associated with the street address, designates the street address as a validated emergency contact location for the user identity in response to determining that the expiration date associated with the street address has not expired. The system thereafter permits the establishment of communications between the system and a disparate wireless network device associated with a multicarrier wireless network.

  • Publication number: 20150094016
    Abstract: Efficient processing and/or routing of emergency calls in an IMS (IP Multimedia Subsystem) for VoIP (Voice over IP) subscribers can be enabled. In one aspect, an E911 profile is generated, for example, by an application server, for each VoIP subscriber based in part on current location information associated with the subscriber, such as, the subscriber's IP address. The E911 profile is pushed to the HSS (Home Subscriber Server) of the IMS. The E911 profile can then be stored in the HSS and can be queried by an E-CSCF (Emergency Call Session Control Function) during emergency call processing. Moreover, when an emergency call is received from the subscriber, the E-CSCF can retrieve the E911 profile associated with the subscriber from the HSS and route the call to an appropriate PSAP (Public Safety Answering Point) based on an analysis of the information in the E911 profile.
